Chung Metal’s Aluminium 2024 bars and rods are high-strength, aircraft-quality products mainly alloyed with copper. Made in Da Nang, the rods/bars are precision machined and finished to serve critical aerospace, defense, and structural uses. Aluminium 2024 has good fatigue resistance and high tensile strength, making it suitable for load-bearing parts. Although less corrosion resistant than other alloys, it excels in dry environments. Chung Metal guarantees every batch is heat-treated and inspected to satisfy global mechanical and metallurgical standards, ensuring our 2024 bars/rods are a reliable selection for sophisticated engineering uses.
Aluminium 2024 has around 4.4% copper, 1.5% magnesium, 0.6% manganese, and rest aluminium. It is a heat-treatable, high-strength, and fatigue-resistant alloy. Tensile strength: 470–520 MPa, yield strength: 320–400 MPa, elongation: ~10–15%. Brinell hardness: ~120–130 HB. It possesses poor corrosion resistance, particularly in marine conditions, and may need to be clad or coated. Not weldable using normal techniques. It is nevertheless lightweight, strong, and good for use in fatigue-critical parts.

Yes, Aluminium 2024 can be welded, but it is challenging due to its susceptibility to cracking. Specialized techniques like TIG welding with proper filler material and preheating are recommended for best results.
To maintain Aluminium 2024 bars, regularly clean with mild detergent, avoid exposure to harsh chemicals, and apply protective coatings. Store in dry conditions to prevent moisture and corrosion, ensuring longevity.
Yes, Aluminium 2024 can corrode, especially in harsh environments. It has moderate resistance to corrosion, but its susceptibility increases without proper protective coatings, making it prone to pitting and stress corrosion cracking.
Aluminium 2024 rods/bars are extensively applied in aerospace structures like fuselage structure, wings, gear components, and engine mounts. In automotive and racing car components, utilized for chassis parts and suspension parts. Also utilized in military-grade parts, aircraft fittings, truck wheels, and structural uses requiring high strength-to-weight ratio. In industrial equipment, it is ideally suited in hydraulic applications, actuator parts, and stressed mechanical parts. Nevertheless, it is optimally utilized in dry environments or with protective coatings.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
